Executive brief
Snipe-IT is an open-source asset management system used to track IT hardware and inventory. A user with custom field creation privileges can inject malicious code into a field name, which executes in the browser when any user (including administrators) views the asset list. This allows a lower-privileged attacker to run code in an admin's session and grant themselves full administrator access.
Technical details
The vulnerability is a stored cross-site scripting (XSS) flaw in the asset list column headers. A user with the "customfields.create" permission can create a custom field with an HTML/JavaScript payload in its name (e.g., `<img src=x onerror=alert(1)>`). When the asset list page (/hardware) is rendered, the field name is passed to the bootstrap-table JavaScript plugin via the data-columns attribute without proper escaping. The bootstrap-table plugin renders the header title unescaped because its global escape option defaults to false. The vulnerability requires the attacker to have "customfields.create" permission (which can be granted to non-superusers) and the target to associate the custom field with an asset model. No user interaction is required—the payload executes automatically on page load. The patch was released in commit 58754e4.
